I'm also a quantity over quality guy. I like to ride my bike, I have a 1 hour commute each way that is hilly so 8-12 hours/week, but I only "train" 2-3 times a week so ~2.5 hours of active training time. Could I cut out a bunch of hours in there and be as strong or stronger with a more structured program? Sure, but I like riding my bike and enjoying the scenery. Being fast and racing is but a small aspect of my riding.
